I am using the telerik.RadTreeView in my WPF-Application.

Beginning of september I updated the Telerik.Windows.Controls (current version is 2019.1.114.45, unfortunately, I can not say right now which version it was before).

Now we have found out, that since these update, the SelectionChanged event is no longer triggered by touch if ScrollViewer.PanningMode="VerticalOnly" is set. Mouseclicking still triggers the event.

Since this is some old (and not my code), removing ScrollViewer.PanningMode="VerticalOnly" solved this problem and I can't figure out a different behavior for scrolling, so i can go with that.

I would still be interested, if you can tell me,why this error occurred.

Best regards

Hello Frank,

With the R2 2015 release, we started using the TouchManager to handle the touch operations inside the RadTreeView control. It seems, however, that this new approach does not work along with the ScrollViewer.PanningMode property.

I have thus logged a new bug report in our feedback portal regarding this on your behalf. As a thank you for your help, I've awarded you with some Telerik points.

I do hope that you find not using the ScrollViewer.PanningMode possible for you for the time being.
